Baltimore- last minute Monday night restaurant rec!

I have some friends in town tonight and can't find a restaurant open on Monday that seems to fit our needs! We're looking for something along the lines of Salt/Bluegrass/Peter's Inn/Tapas Teatro- cool, fun spaces with great food, in the downtown/Fells/Federal Hill/Canton/Midtown, etc. regions (i.e. nothing too far away from downtown, not Hampden/Roland Park, etc.). Two non-drinkers and a pregnant lady are coming so alcohol is not important and no sushi.

I was there 2 weeks ago and had an amazing dinner at Thames Street Oyster House in Fells. See about availability of eating upstairs which is way more quieter than the bar upstairs. Very diverse menu with many seafood options (all cooked) and some other non-seafood dishes. I personally loved both entrees that we ordered, crabcake and ciopinno.
